Measuring Value in Global Value Chains

Rashmi Banga

Abstract: This paper compares alternative ways of measuring participation of a country in

Global Value Chains (GVCs) and estimates distribution of gains between countries in terms of

countries' shares in total value-added created by trade under GVCs. It further shows that

conclusions and implications of linking into GVCs can change drastically, especially for

developing countries, with alternative ways of measuring participation in GVCs. Gains from

linking in GVCs in terms of net value-added exports are estimated for different countries. Sector

wise analyses is undertaken to assess the importance of GVCs to developing countries. Using the

OECD-WTO database on Trade in Value Added (May 2013) the paper shows that 67% of total

global value created under global value chains accrue to OECD countries while share of NICs

and BRICS countries is 25%. Only 8% of total value added is shared among all other developing

countries and LDCs. Forward linkages (i.e., domestic value-added exports of a country which

goes into exports of other countries) and backward linkages (foreign value added in gross exports

of a country) in GVCs are estimated for all countries. It is found that in case of US, Japan and

UK, forward linkages are much stronger than backward linkages, indicating net value-added

gains from linking into GVCs. China and Korea, on the other hand, have negative net value

added gains. Other developing countries, like India, Viet Nam, Thailand, Malaysia and

Philippines also have less than one ratio of forward to backward linkages in GVCs. Examining

the structure of exports in different countries and gains from participation in GVCs, the paper

argues that it may not help to trade more without compensating gains linked to production

activities and creation of domestic value added. It is therefore important to ‘gainfully link into

GVCs’ in identified industries where the country is able to derive net positive domestic value

added gains.

Measuring Value in Global Value Chains

Rashmi Banga

1. Introduction

The trade-led-development debate has become even more complex with the rise of global value

chains (GVCs) that have fragmented production processes across countries and continents and

boosted network trade. Developing countries are finding it hard to assess their relative gains from

trade. Nevertheless, 'linking into GVCs' per se is increasingly being considered as the new

development challenge by policy makers in many developing counties. Industrial policies are

being reshaped in order to adjust to this new dimension of trade; and foreign direct investments

are being encouraged with the hope of raising the possibility of linking into the value chains. In

this race to link into GVCs, very little attention is being paid on measuring the additional gains, if

any, to the country by linking, especially in terms of 'net value-added' created by trade within

GVCs. One of the probable reasons for this is the lack of conceptual clarity on what trade can be

categorized as trade under GVCs and how to measure this trade at the country level. Distribution

of gains under GVCs in terms of value added created across countries is yet to be measured.

With the growing inter-linkages in trade where trade in intermediate products is growing faster

than trade in finished products; common intermediate products are being used across industries;

and value-chains are extending beyond products to include services component as well, almost

every exported finished product uses some inputs which has an imported content. This limits the

use of the traditional tools like 'import content of exports' or 'intra-industry trade' in estimating

extent of trade under global value chains.

These issues have led to a growing consensus that trade data is unable to capture the net value-

added1gains under international fragmentation brought by GVCs, mainly because the trade

statistics were designed to capture trade flows in final products while the share of intermediate

trade is now growing at a faster rate than that of final goods trade. The use of trade data often

leads to double counting due to this growing network trade, where intermediate products cross

boundaries frequently. The splintering of many services from manufactured products and rising

1 Value-added is defined as value of output minus value of inputs

share of services in trade has further limited the use of trade data. Studies have been suggesting

for the past three decades that any analyses with respect to gains from trade need should be based

on net value-added by trade (Porter 1985, Kogut1985). Likewise, comparative advantage which

was typically expressed in terms of products/industries according to the earlier trade models; now

requires to be based on activities and tasks (Gereffi,1999).

To measure net domestic value added created by trade, input-output (I/O) analyses provide a

useful alternative to trade data. An important advantage of I-O tables is that they classify goods

according to their use (as input into another sector’s production or as final demand); and include

information on inputs of/in services sectors, allowing for the analysis to include services trade.

OECD-WTO in May 2013 released its dataset on Trade in value-added (TIVA) for 58

countries(including all OECD countries; BRICS countries; NICs1; NICs2, Cambodia, Brunei

Darussalam and ‘Rest of the world’) for the years 1995, 2000, 2005, 2008 and 2009 using

harmonized input-output tables of these countries. UNCTAD has extended this to include

developing as well as least developed countries2.

While these databases should be able to provide more precise ways of estimating 'gains from

trade in GVCs' in terms of value-added, the debate has now focused on the manner in which

'participation in GVCs' can be estimated. This brings to the forefront issues with respect to

measuring trade in GVCs and distribution of value-added gains between countries linked in

GVCs.

This paper compares alternative ways of measuring participation of a country in GVCs and

estimates distribution of gains between countries in terms of countries' shares in total value-

added created by trade under GVCs. It further shows that conclusions and implications of linking

into GVCs can change drastically, especially for developing countries, with alternative ways of

measuring participation in GVCs. Gains from linking in GVCs terms of net value-added traded

are estimated for different countries. Sector wise analyses is undertaken to assess the importance

of GVCs to developing countries.

2. Evolution of GVCs and Value-Added Trade

Global value chains first emerged as regional supply chains in East Asia, with Japanese investors

taking the lead in the region and triggering flying geese pattern of investments and trade.

Japanese investors put up production bases in a large number of countries in East Asia and later

in Southeast Asia to access locational advantages and develop export platforms for the

components. The final assembly took place in a third country from where the finished products

were exported either back to the home country or to the global markets under the Japanese brand.

This fragmentation of production improved the cost competitiveness of the final products which

were then able to compete with the products from other developed countries. Overtime

multinationals from other developed countries, aiming at improving their cost competitiveness,

flocked the region and soon spread to other regions as well. What emerged from this

phenomenon were global value chains (GVCs) with production of a product spread across

countries, regions and continents gathering cost advantages to become globally competitive.

GVCs played an important role in boosting network trade. World network trade increased from

US$ 988 billion (about 44% percent of total manufacturing exports) in 1990-91 to US$ 4.5

trillion (51%) in 2009-10, accounting for over 60% of the total increment in world manufacturing

exports during this period3. Although, GVCs have increasingly embraced network trade, they go

much beyond network trade4 as all the activities under the production process, beginning from

research and development activities, product designing, sourcing of primary products, production

of intermediate products, final assembly of the product, packaging, branding and marketing of the

product, etc are now being split and undertaken in different countries/continents. The value

chains therefore include full range of activities and processes that are needed to bring a product

from conception through the intermediary stage of production to delivery to final consumers and

final disposal after use5.From this definition, a global value chain can be simply understood as

the sequence of all functional activities required in the process of value creation involving more

than one country. GVC for a particular product may therefore not only span over countries but

also span across different industries including services.

3Athukorala and Nasir (2012), Global Production Sharing and South-South Trade, UNCTAD

4 Network trade refers to trade in both 'parts and components' and 'final assembly.' Trade in final assembly is arrived

at by deducting trade in parts and components from total value of trade. 5Kaplinsky and Morris (2001) A Handbook for value chain research, IDRC

Page 7: MEASURING VALUE IN GLOBAL VALUE CHAINS · 2013-05-29 · 1 UNCTAD REGIONAL VALUE CHAINS BACKGROUND PAPER MEASURING VALUE IN GLOBAL VALUE CHAINS Rashmi Banga UNIT OF ECONOMIC COOPERATION

Given the above conceptual definition of GVCs, measuring gains from trade from GVCs using

product level trade data becomes virtually impossible. Harmonized input-output tables of

different countries are used to estimate the domestic value-added and foreign value-added created

in manufacturing as well as services sectors when a product is exported from a particular country.

These tables therefore help in estimating the 'domestic value-added’ content in gross exports of a

country. ‘Domestic value-added exports' will therefore differ from ‘Gross exports’ and can be

estimated by subtracting foreign value-added, i.e., value added created in other countries that is

imported and enters exports of the country. Correspondingly, global value-added exports can be

arrived at by summing domestic value-added exports of all countries. This sum nets out double

counting in global trade, which is caused by export and re-exports of intermediate products in

network trade.

In 2009, world gross exports amounted to USD 17.05 trillion. However, world value-added

exports amounted to USD 13.7 trillion(around 19% lower than gross exports), emphasizing the

extent of double counting in total trade due to network trade. While, world gross exports as a

proportion of GDP increased from 19% in 1995 to 25% in 2005 and 29% in 2009, world value

added exports were much lower and increased from16%, 18% and 24% in 2009. In 2009,

following the crisis, while increase in world exports as a proportion of GDP appeared to be only

one percentage point, the actual increasein terms of value added exports was 3 percentage points

(Table 1).

The extent of difference between gross exports and value-added exports w hich is foreign value

added in gross exports, varies across countries depending on country’s engagement in network

trade. The difference in gross exports and value-added exports is most prominent for Newly

Industrialized countries tier 1 (NICs1) countries like Singapore (50%), Chinese Taipei (42%),

Korea (41%); followed by NICs 2 - Malaysia (38%), Philippines (38%), Thailand (35%); then

China (33%), Hong Kong China (28%). For most developed countries foreign value added in

gross exports is less than 30% with UK- 17%; USA -11% and Germany -27%. For BRICS

countries, especially Brazil and Russian Federation, this difference is lower as they export high

proportion of commodities. The difference for India and South Africa is 22% and 16%

respectively.

Trends in share of domestic value addition in gross exports, which is indicative of the value

added gains for a country from exports, for the period 1995-2010, reveal interesting insights

(Figure 2). Domestic value added in gross exports has declined substantially for many

developing countries indicating rise of foreign value addition in their gross exports. However, for

some countries domestic value added has increased in this period. These are UK, Italy, Malaysia,

Russian Federation and Hong Kong China. Decline in USA has been marginal (3 percentage

points) but very high for countries like China (21 percentage points), Korea (17 percentage points)

and India (12 percentage points).

The share of services value-added exports in global value added exports has increased at a faster

rate than manufactured products. It rose from 46% in 2005 to 66% in 2009.Maximum percentage

increase in share of services in value-added exports is in the case of Germany and UK (Figure 3).

In 2009, share of services in total value added exports was around or greater than 50% for most

of the developed countries in the selected list of countries, while for most of the developing

countries it was 40% or less, except for India where it reached 53%. In countries like China,

Indonesia, Thailand, Viet Nam and Malaysia, the share of services in their gross exports is found

to be less than 40%.

Foreign value added (FVA) in gross exports of a country reflects the total value-added created in

other countries which enters the exports of a country. This differs from 'import content of exports'

in three important ways, first this will not double count as it includes foreign value-added in all

inputs of the products only once and the number of times the inputs cross borders will not affect

its calculation. It also includes services component that enters the value addition; second in multi-

country value chains, it will contain not just the foreign value added content in bilateral trade but

will also contain foreign value added included in exports of the country's bilateral trading partner.

For example, if China imports intermediate products from Vietnam, FVA content in China's

exports be will sum of value added created in Vietnam as well as value added created in other

countries from where Vietnam imported its inputs for producing its intermediate product.It

therefore includes all direct imports as well indirect imports (from countries where there is no

direct trade). This can have important implications for bilateral trade balance. Third, the re-

imported domestic value added will be netted out.

gross exports is found for NICs1 countries, i.e., Singapore, Chinese Taipei and Korea. This is

followed by NIC2 countries, mainly Philippines, Malaysia and Thailand. Mexico and Viet Nam

have experienced a steady rise in share of FVA in gross exports while there has been a steady

decline in case of Hong Kong China.

Shares of FVA in gross exports for most of the developed countries have remained less than 30%,

while that of Japan, USA, UK and Australia has remained less than 20%. This brings us to the

question of whether FVA in gross exports is an appropriate indicator to measure the extent of a

country’s participation in GVCs? We examine this issue is some detail in the next section.

3. 'Participation in GVCs' and 'Distribution of gains'

3.1 Measuring Participation in GVCs

GVCs cut across industries, countries and are increasingly using services from different services

industries. Advancements in ICT have added new dimensions to trade, as many services which

were earlier included in the production process can now be off-shored. One of the challenges

facing developing countries in this scenario is to estimate their extent of participation in GVCs

and the net value-added gains from this participation. However, underlying this estimation issue

is the conceptual issue of what part of trade can be categorized as trade under GVCs? This may

be less complicated to measure at the firm level, where the lead firms may be able to identify

their value chains but more complicated at the country level.

Literature on GVCs uses the measure of ‘vertical specialization’6

to gauge a country's

competitiveness in GVCs. Studies have estimated vertical specialization separately for

intermediate and finished products (Hummels, et al, 1998, 2001, Chen et al., 2005)to arrive at the

relative competitive position of a country in the value chains. Although this is a better measure as

compared to 'import content of exports' it is unable to capture the extent of participation of

different countries in GVCs and their relative gains.

Distribution of gains across countries under GVCs is an important issue which may highlight the

importance of GVCs for developing countries. Many studies have pointed out that gains are

unevenly distributed across the value chains (Gereffi (1994), Kaplinsky (1998), Schmitz (2006).,

Fitter and Kaplinsky (2001), Kaplinsky and Fitter (2004), Kaplinsky (2005),Milberg 2009). The

balance of power often favors nodes with high technology (which would imply that firms which

6 Vertical specialization occurs when a country uses imported intermediate parts to produce goods it later

exports. This definition captures the idea that countries link sequentially to produce final good.

control technology through mechanisms like patents or licenses are in extremely powerful

positions and are likely to extract maximum rents in GVCs). But technology may not be

sufficient to maximize rents in value chains as higher rents may also accrue to nodes with better

organizational skills and better marketing capabilities with use of brand names. To extract

maximum rents, governance becomes an important ingredient in the value chain. Governance

ensures that activities, actors, roles and functions in the value chain are organized in a manner

that rents are maximized.

Gereffi and Korzeniewicz's (1990) elaboration of the commodity chain concept illustrates that in

low-wage labor-intensive production (in their case of footwear), the principal profits are not

realized in manufacturing itself, but rather in the corporate coordination and control of the entire

'global assembly line', especially design, marketing and retailing - activities that are typically

controlled by transnational firms based in core countries. In this complicated chain of events and

functions, peripheral countries many times remain primarily 'export platforms' for simple low-

technology, labor-intensive goods made by low-wage unskilled workers. This adds to the

challenge of overcoming 'technological dependence' for non-core countries – even for East Asian

NICs that are relatively technologically advanced. This explains why Indonesian factories that

subcontract to produce huge quantities of the latest models of Nike sports shoes retain only a tiny

proportion of the global corporation profits on the shoes (Ballenger, 1992). Case studies for

China show that for Apple iPod, only USD 4 out of the total value of USD 150 can be attributed

to producers located in China while most of the value accrues to US, Japan and Korea (Dedrick,

Kraemer and Linden2009). Although case studies point out the uneven distribution of gains in

GVCs, very few studies estimate the extent of countries' participation in GVCs and the

distribution of total value-added gains under GVCs across countries.

This paper seeks to measure the extent of a countries 'participation in GVCs and their relative

gains by estimating their share in total value-added created by trade in GVCs. It's important to

focus on relative gains to a country along with its participation in GVCs as participation in itself

may not necessarily bring gains in terms of higher net domestic value-added created by trade.

For a particular country, especially a developing country, linking into GVCs could either be

through forward linkages (where the country provides inputs into exports of other countries) or

through backward linkages (where the country imports intermediate products to be used in its

exports). Using this sequential production process definition of participation in GVCs, for a

particular country this could be measured as a sum of 'foreign value added in its gross exports'

(backward linkage or imports of foreign value-added) and its 'domestic value-added which goes

into other countries' gross exports' (forward linkage of export of domestic value-added). Share of

a country in total value-added created by forward and backward linkages in GVCs (i.e., summing

over all countries) can provide a measure of extent of a country’s participation and its relative

gains in GVCs. Using OECD-WTO TIVA dataset(May 2013),participation in GVCs is estimated

for each of the 58countries (34 OECD countries); 5 BRICS (Brazil, Russian Federation, India,

China and South Africa); NICs (8 countries);and the category 'rest of the world' which comprises

all developing and under-developed countries excluding BRICS and NICs.

Figure 4 shows the distribution of global value added created by GVCs in 2009. Share of OECD

countries in total value-added created by GVCs is found to be 67%, share of NICs1 is around 8%

and NICs 2 around 3%. BRICS countries comprise 14%, of which share of China is 9%. While

share of rest of the world, which includes all LDCs and other developing countries

(excluding NICs and BRICS), is 8%.Within, OECD countries, share of top six countries - US

(9%), Germany (9%), UK (4%), Japan (4%), Korea (5%) and France (4%) is around 35%.Adding

China to this list would imply explaining almost 45% of global value added created by GVCs.

Between countries, maximum participation in GVCs, in terms of share in total value-added

created in GVCs is of China (9%)and US (9%). Excluding the share of China, BRICS share is

only around 5%. All other developing countries together share less than 10'% of global value

added created by GVC participation. Further, if share of China is estimated in terms of total

participation of developing countries in GVCs, it is as high as 30%. Share of China in backward

linkages of OECD countries with developing countries (i.e., FVA by China in OECD countries

gross exports as a proportion of FVA by all developing countries) is as high as 33% while share

of China in forward linkages of OECD countries with developing countries (i.e., domestic value-

added of OECD countries in exports of developing countries) is 34%. FVA from OECD countries

in China's gross exports amounts to 78% of its total FVA in gross exports while it contributes

around 65% of its value added exports enter gross exports of OECD countries. This would imply

that gross exports of China create much more value-added in developed countries as compared to

developing countries. Since most of the GVCs emerge from OECD countries, China can be

called the epicenter of GVCs in the developing world for developed countries.

3.2 Measuring Distribution of Gains in GVCs

Higher participation in GVCs may not ensure higher gains. A break-up of forward linkages and

backward linkages in GVCs can provide a useful insight into the gains that go to a country from

its participation in GVCs. If gains are measured in terms of 'net value-added' by participation in

GVCs, then higher the forward linkages as compared to backward linkages, higher are the gains.

This would imply that by its participation in GVCs, a country is creating and exporting more

domestic value-added than the foreign value added which it is importing. The ratio of forward to

backward linkage therefore can be a good estimate of the extent of net gains (Table 3).In terms of

participation in GVCs, China, USA and Germany have the highest participation rate (9%),

followed by Japan (4.5%) , France (4%) , Korea (4%) , UK (4%) and Italy (3%).

Participation in forward linkages of GVCs, which is the extent of domestic value-added that enter

exports of other countries, is found to be highest for US (12.6%) followed by Germany (8%);

while share of FVA in exports, i.e., backward linkage is found to be highest in China (12.6%)

followed by Germany (9.3%). Ratio of the two shares for a country indicates country’s net gains

in terms of value-added by participating in GVCs. High participation in GVCs (greater than 3%)

and a ratio of forward linkage to backward linkage higher than 1 is found for US, Japan, UK and

Italy. However, if a country is exporter of commodities or primary inputs, its forward linkages

will be much higher than its backward linkages like in case of Russia, Brazil, South Africa and

Indonesia. But these countries will correspondingly show low participation in GVCs.

US, Germany and China have high total participation in GVCs. US has much stronger forward

linkages as compared to its backward linkages (ratio of 2.53)implying that GVCs create higher

net domestic value-added in US and its domestic value-added which enters other countries’

exports are much higher than the foreign value added that enters exports of US. The ratio is 0.5

for China indicating that China’s domestic value-added that enters other countries’ exports is

much lower than what it imports from other countries. This substantiates the results arrived at by

the case studies on China.

4. Structure of Gross Exports in terms of Value-Added

The manner in which 'participation in GVCs' is defined can give completely different results

depending on which part of GVCs is focused on. Earlier literature has mainly focused on import

content of exports. Figure 5 shows the structure of gross exports of the world. Domestic value

added by manufacturing contributes the maximum proportion of gross exports globally

contributing 43% of total gross exports while domestic value added services contribute 33%.

FVA which constitute global value chains comprise 24%, of which 10$5 is contributed by

services sectors. Share of FVA in manufacturing, where all developing countries can hope to gain

constitutes only 14% of total gross exports. This 14% of value added is divided among developed

as well as developing countries.

Figure 5: Structure of Global Gross Exports: 2009

In value-added terms, studies have focused on FVA in gross exports. However, for cross-country

comparisons these indicators can clearly give a misleading picture. Figure 6 exhibits the structure

of gross exports of some countries. In terms of FVA in gross exports, US appears to be one of the

least integrated countries in GVCs as the proportion of FVA in its gross exports was only around

19

11% while a country like India, whose share in global value-added in GVCs is less than 2% may

appear to be more integrated than US and Japan.

The second component of GVCs which is the ‘forward linkages’ shows the extent of domestic

value-added that enters exports of other countries. This may reveal direct gains from GVC

participation in terms of domestic value addition. For Japan, US and UK the proportion of

domestic value-added exports in forward linkage in GVC is an important component of their

gross exports. Share of forward linkage of GVCs in their gross exports is between 25%- 30%. In

other words, forward linkages create around 30% of domestic value-addition in their exports.

China although appears to be integrated at a much higher level in terms of backward linkage, its

forward linkages are not as strong in its gross exports in terms of creating domestic value-added.

In fact, its domestic value-added exports used in other countries' exports in GVCs are one of the

lowest in the selected countries. For countries that export commodities and other primary inputs,

only forward linkages may not correctly show their extent of GVC participation as most of their

domestic value-added exports will enter exports of other countries, e.g., in case of Russia, this is

46% and around 29% for Indonesia and Brazil.

The category of domestic value-added exports of 'final products' or consumption goods which

caters to final demand in other countries is still significant in most of the countries. Another way

at looking at it could be that the importance of getting linked into GVCs for boosting exports for

developing countries may have been over-emphasized as domestic value-added exports which

cater to final demand of other countries are much higher even for countries with high

participation in GVCs like China or US. Getting linked to GVCs in forward linkages may be used

as a strategy for boosting growth in industries which are not competitive in exports of finished

products but may not be the right strategy for all industries. However, backward linkages may be

useful for improving cost competitiveness of gross exports. But again, this linkage may not

necessarily boost domestic value-added exports. Example of Korea with high backward linkage

(41%) and relatively high forward linkage (24%) shows that its domestic value-added exports of

final products are the lowest.

5. Role of Services in climbing-up the global value chains

Share of services in global trade is rising rapidly and so is the role of services in GVCs.

Improvements in technology, standardization, infrastructure growth, rapid advances in ICT and

decreasing data transmission costs have all added to tradability of services. Developing on Porter

(1985) value systems, studies like Gereffi (1999), Mitsuhashi (2005) and Mudambi (2007) have

emphasized that functional upgrading in GVCs gives highest rents. The much discussed 'smiley

curve' posits that activities which essentially involve services like applied Rand D, design and

marketing, recreate higher returns than the manufacturing function. They reinforce the arguments

made by Gereffi and Korzeniewicz's (1990) that the principal profits are not realized in

manufacturing itself, but rather in the corporate coordination and control of the entire 'global

assembly line'.

Given the important role played by services in upgrading in GVCs, contribution of services in

global value-added is estimated for each country using the input-output tables. It is found that

services contribute 45% to global value-added exports. However, this differs significantly across

countries. Figure 7 breaks down the gross exports of different countries into FVA by

Page 21: MEASURING VALUE IN GLOBAL VALUE CHAINS · 2013-05-29 · 1 UNCTAD REGIONAL VALUE CHAINS BACKGROUND PAPER MEASURING VALUE IN GLOBAL VALUE CHAINS Rashmi Banga UNIT OF ECONOMIC COOPERATION

21

manufactured products; FVA by services; domestic value-added by manufactured products and

domestic value added by services.

Figure 7: Value Added by Manufactured Products and Services in Gross Exports

Source: OECD Stat and OECD-WTO TIVA, May 2013

For OECD countries, contribution of services in value-added exports is almost 50%. Out of this,

39% is sourced domestically and 11% is sourced from other countries. For BRICS countries

value addition from services in their total value-added exports is 33% of which 8% is sourced

from other countries. In China, most of the value-added by exports is created in the

manufacturing sector, services contributed 29% of total value added exports in 2009, with 40%

imported from other countries. While in India, most of the value-added exports are from the

services sector contributing 53% to value-added exports. Foreign value added from manufactured

products and services is almost equal in case of India. In other developing countries like

Indonesia, contribution of services is less than 20% with only 5% of value-added contributed to

its exports from other countries.

What is striking in the above analysis is the fact that services play a much more dominant role in

value-added contribution to exports of developed countries as compared to the manufactured

products. Overall, in OECD countries, contribution of domestic value-added to total exports from

services is greater than contribution of domestic value-added to exports by manufactured

products, with higher share of services seen in case of US, France and UK. Domestic value-added

in exports by manufactured products play a dominant role in developing countries. The backward

linkages in services are also not strong for developing countries. As discussed, if most of the

rents in GVCs come from shifting to services component of manufactured exports, developing

countries may stand little chance in maximizing gains through functional up-gradation in the

value chains.

6. GVCs bypass Low-Tech industries

Low–tech industries which are the major job creators in most of the developing and least

developed countries have not experienced much production fragmentation brought by GVCs as

seen in high-tech and medium-tech industries like Electrical and optical equipment; Machinery

and equipment; Transport equipment; and Chemicals. Figure 8 shows the share of foreign value

added entering exports of low-tech and high-tech industries in different countries. While in

developed countries GVCs are expected to concentrate in high-tech industries, in developing

countries like BRICS, as well as other developing countries (NICs1and NICs2 ), the share of low

tech industries is very small in total FVA entering gross exports. In China, total gross exports

included 28% of foreign value-added of which only 15% entered low-tech industries.

Note: High tech industries comprise -Electrical and optical equipment; Machinery and equipment, nec; Transport

equipment; and Chemicals and non-metallic mineral products and low-tech industries comprise- Textiles, textile

products, leather and footwear; Wood, paper, paper products, printing and publishing; Food products, beverages and

tobacco; Agriculture, hunting, forestry and fishing; Mining and quarrying; and Manufacturing nec; recycling

Comparison of backward linkages, i.e., FVA in gross exports in different sectors of China, India

and US shows that while in services sectors, India has higher share of FVA in gross exports, in

manufacturing sectors China has higher share. US has lower share of FVA in its gross exports

and higher domestic value added share as compared to China and India in almost all sectors. In

manufacturing recycling, India has experienced a much higher high share of foreign value added

in its gross exports as compared to other sectors. in low tech sectors like textiles, textile products,

leather and leather products; wood, paper, paper products etc; and food products, beverages and

tobacco, VA in gross exports in China and India is higher than that in US.

Even in case of high-tech industries, participation of developing countries in GVCs may not

ensure net gains in terms of value-added created by trade (Table 3). The net value-added in

exports in GVCs is positive in case of developed countries. In machinery and equipment,

domestic value added of US entering exports of other countries is higher than foreign value added

in exports of US. Japan and UK also experiences a net gain in its participation in GVCs. China’s

participation in machinery and equipment, although in this sector for other developing countries

like India, Thailand, Philippines and Viet Nam the ratio is greater than 1. US, Japan and UK

experience net gains by their participation in GVCs in chemicals and non-metallic mineral

products. In low-tech industries, like textiles, textile products, leather and footwear Italy’s net

gains from participation in GVCs are higher than that of China’s. India has a greater than 1 ratio

in all the three sectors. A plausible reason for this is that India exports inputs of these sectors and

has low participation rate in terms of backward linkages.

Structure of Value-Added Exports of China in Electrical and optical equipment

China is one of the biggest exporters in Electrical and optical equipment. In 2009, its exports

were of the tune of USD 466 billion out of USD 1.7 trillion total world exports. The domestic

value-added in exports of China was only 57% of its total exports. While, Foreign value-added

generated by its exports comprised 33%. The share of different countries in gross exports of

China is depicted in Figure 10. Maximum value added is created in Japan (6%) by Chinese

exports in this sector, followed by US, Chinese Taipei and Korea (5%).

Structure of Value-Added Exports of China in textiles, textile products, leather and footwear

In textiles, textile products, leather and footwear, one of the low-tech industries which has often

been identified as an industry with prominence of GVCs, the breakup of gross exports of China

reveal interesting insights. China's share in global exports of this sector is 40% while its share in

developing countries total exports is 64%. In 2009, China's gross exports comprised USD 218

billion, of which foreign value added was USD 32 billion (15%). China's backward linkages are

found to be stronger with the developed countries as compared to developing countries, with

relative share of US Japan and Korea being around 10% each. While, China’s contribution of

value-added to developing countries exports is found to be relatively higher as compared to

developed countries.

What emerges from the sectoral analyses of value-added created under linkages in GVCs is that

high-tech industries have much higher fragmentation of production processes and existence of

GVCs as compared to low-tech industries. Domestic value-added in high-tech industries in

developing countries may not be very high. Even in industries where developing countries like

China have highest share in global exports, e.g., electrical and optical equipment, a large part of

value-added is sourced from developed countries from where most of the TNCs emerge. In low-

tech industries, like textiles and leather, although comparative advantage of developing countries

is higher by definition as they involve large-scale low-wage employment, the backward linkages

with developed countries in terms of foreign value-added used in exports is higher as compared

to developing countries. The gains of exports are therefore being fragmented along the global

value chains with the balance of power favoring developed countries.

7. Gainfully Linking into GVCs

Another way of assessing gains in terms of value-added to a country from its participation in

GVCs can be by comparing the country's performance over the years in terms of percentage

change in its exports to GDP ratio and percentage change in its domestic value-added content in

its exports and seen in conjunction with a country's participation in GVCs. Thiscan point out the

direction in which the country is heading in terms of gaining from its participation in GVCs.

Table 5 tabulates the percentage change in exports to GDP ratio in 2009 over 2005 along with

percentage change in domestic value-added in exports of a country in the same period. Column 3

shows the participation of countries in GVCs in 2009, in terms of their shares in total value-added

in GVCs. Countries that appear to have gained from their participation in value chains will be

Page 28: MEASURING VALUE IN GLOBAL VALUE CHAINS · 2013-05-29 · 1 UNCTAD REGIONAL VALUE CHAINS BACKGROUND PAPER MEASURING VALUE IN GLOBAL VALUE CHAINS Rashmi Banga UNIT OF ECONOMIC COOPERATION

28

those which have experienced positive percentage change in their exports to GDP ratio as well as

in their proportion of domestic value-added in their exports along with high participation. These

countries are Switzerland and United States. South Africa and Mexico have experienced positive

changes in the two ratios but low participation in GVCs indicating that this gain may not

necessarily come from GVC participation.

China's participation in GVCs is the highest; it has also gained in terms of percentage change in

domestic value-added in its exports but its exports to GDP ratio has declined by 9 percentage

points in 2009 as compared to 2005. Similar is the case for Russia, although its change in

domestic value-added in exports is much lower than China’s and it has much lower participation.

Performance of other BRICS countries shows that participation of Brazil is low in GVCs but it

has gained in terms of domestic value-added in exports. India on the other hand has low

participation in GVCs but although it has improved its exports to GDP ratio, its domestic value-

added content in exports has declined.

Korea and Japan have high participation in GVCs but do not seem to have gained in terms of rise

in domestic content in exports. Korea’s exports to GDP ratio increased by almost 10 percentage

points in 2009 over 2005 but its domestic value-added in exports declined by almost 5 percentage

points. Japan has experienced a fall in both the ratios.

Country experiences show that higher participation in GVCs may lead to rise in exports to GDP

ratios but may not necessarily lead to rise in incomes and employment in the long run if it is not

accompanied by rising domestic value-added content in exports. For small countries with limited

size of domestic markets, external demand can play an important role in growth of their GDP.

Linking into GVCs provides the opportunity to increase production and create employment in

those industries where the country may not have the comparative advantage in producing the

final products but has the locational advantages in production of its intermediate products. These

locational advantages can be in terms of low cost labour, possession of particular skills or factors

like land, or policy induced favorable environment. These advantages may help a country to link

into GVCs but may not help the country in climbing the value chains and deriving dynamic gains

8. Summary and Conclusions

Linking into GVCs is increasingly being considered as the new development challenge by many

policy makers, especially in the developing countries. GVCs are expected to bring gains to the

linked countries in terms of improved competitiveness, better access to global markets and

expansion of production and jobs in these countries. However, whether countries realize these

gains or not is still not clear mainly because the tools to measure a country’s extent of

participation in GVCs and distribution of incomes generated in GVCs across countries are

limited. The rising share of intermediate products in total trade has challenged the use of

traditional tools like export shares in assessing countries’ competitiveness. Higher export shares

may not necessarily imply higher competitiveness if exports contain a large share of imported

intermediate products. In similar fashion, higher exports may not guarantee more domestic

production and more jobs if domestic value-added content of exports does not rise.

To address these issues and provide some measure of the extent of countries’ participation and

distribution of gains in GVCs this paper uses value-added analyses based on harmonized world

input-output tables, provided by WTO-OECD. Using this dataset, value-added exports of each

country are estimated. Value-added exports of a country differ from its gross exports as it nets out

the foreign value-added content in its exports and provides the measure of the extent of domestic

value-added created by exports.

Global value chains include the whole cycle of the organization, production, and delivery of

products from inception to use and recycling. Mostly these chains are initiated by transnational

corporations, and they may begin in developing countries (where primary inputs are sourced) but

end in developed/developing countries (where the branded final products are sold). In the process

of fragmenting production processes they boost network trade. However, they go much beyond

network trade; therefore measures of a country’s network trade may not be suitable indicator of

its participation in GVCs. Foreign value added in GVCs may measure only backward linkages of

a country. If some of the intermediate inputs are imported by a developing country and used in its

exports of consumption goods to final producers, (which is the case for almost all final products

exported by developing countries, as some or the other of its domestic intermediate product will

contain imported content), it cannot be said to be linked into GVCs. To be linked into GVCs,

country’s forward linkages are equally important which measure the extent of domestic value

added which enters exports of other countries.

The paper estimates backward linkages (FVA in exports) and forward linkages (Domestic value-

added which enters other countries’ exports) of each country and estimates countries’ extent of

participation in GVCs in terms of its share in total value-added created by GVCs. The results

show that share of OECD countries is around 61% of total value-added in GVCs; while share of

BRICS countries is 14%; and NICs1 and NICs 2 is around 11%; while rest of the developing and

least developed countries in the world share 8% of total value-added in GVCs amongst

themselves. Participation of China and US in GVCs is highest (9%) followed by Germany

(8.7%), Japan (4.5%) and France, UK and Korea (4%). However, forward linkages (domestic

value-added in other countries exports) are much stronger than backward linkages in case of US,

Japan and UK. China and Korea on the other hand, have stronger backward linkages as compared

to forward linkages. The net value added gains is therefore negative for China and Korea. Other

developing countries, like India, Viet Nam, Thailand, Malaysia and Philippines also have less

than one ratio of forward to backward linkage indicating negative net gains in terms of value

added from GVCs. Exporters of primary products or commodities have naturally higher forward

linkages as compared to backward linkages as their exports are used as inputs in other countries'

exports. However, these countries have low participation rates.

Examining the structure of gross exports in these countries, the importance of exports of

consumption goods to final consumers is revealed. Most of the countries, except for Korea and

commodity exporters like Russia, have more than 50% of total domestic value-added entering

exports for final demand in other countries. Share of consumption goods in total exports is 60%

in US, 52% in Japan and 54% in China, even when these countries have high participation in

GVCs. Most of the developing countries with low participation in GVCs like India still have

more than 58% of domestic value-added in exports going into exports of final consumption

products. Share of Foreign value added by manufacturing sector in global gross exports is only

14%, indicating that value added created through backward linkages in GVCs is only 14% of

global exports which is shared between countries. FVA by services is 10% while the rest of 76%

of value added in exports is domestic value added in different countries. This indicates that

perhaps importance of GVCs in gaining competitiveness and increasing export shares in

32

consumption goods is exaggerated. It may be good to link into GVCs in industries where the

country does not possess competitive advantage in production of final product. Backward and

forward linkages may improve competitiveness of some industries catering to inputs for other

industries, but it may not help to make ‘linking into GVCs’ per sey an objective of industrial

policies. Using backward linkages to improve cost competitiveness of domestically produced

finished products may be a better alternative.

Services play an important role in GVCs. Studies have highlighted shifting of profits from

manufacturing activities to managing and marketing activities in GVCs, which have raised

several issues with respect to governance of GVCs. Higher competitiveness in services of OECD

countries reflects from the fact that for these countries, contribution of services in value-added

exports is almost 50%. Out of this, 39% is sourced domestically 11% is sourced from other

countries. For BRICS countries domestic value addition from services in their total value-added

exports is only 33%, of which 8% is sourced from other countries. In China, most of the value

added in exports is created by the manufacturing sector and services contribute only 29% of total

value added exports, of which 40% is imported from other countries. If competitiveness in

services determines the distribution of profits in GVCs, developing countries stand little chance

to improve their shares in GVCs initiated by developed countries.

GVCs tend to concentrate in high-tech industries, further minimizing the scope for developing

countries to climb the value-chains to increase their share in total incomes generated in the value

chains. Example of China shows that in high tech industries, higher participation in GVCs may

not necessarily imply higher gains. Even if China is the largest exporter in the world in electrical

and optical equipment, its domestic value-added comprises only 57% in its gross exports.

Forward linkages are found to be much stronger in US as compared to its backward linkages in

industries like machinery and equipment and chemicals.

If creating more domestic value-added, output, incomes and jobs from exports are the

development objectives of industrial and trade policies then country experiences show that these

may not necessarily be achieved through linking into GVCs. Countries with high participation in

GVCs have witnessed a fall in their exports to GDP ratios as well as domestic value-added

content in their exports. Korea and Germany are good examples of countries with high

Page 33: MEASURING VALUE IN GLOBAL VALUE CHAINS · 2013-05-29 · 1 UNCTAD REGIONAL VALUE CHAINS BACKGROUND PAPER MEASURING VALUE IN GLOBAL VALUE CHAINS Rashmi Banga UNIT OF ECONOMIC COOPERATION

33

participation in GVCs, rising export to GDP ratio but falling domestic value-added in exports in

2009 over 2005. Japan experienced high GVCs participation, but falling exports to GDP ratio and

falling domestic value-added content in its exports. China has fared better. Although, its exports

to GDP ratio has declined in this period its domestic value-added content in exports has risen.

This can be attributed to strong policy interventions in this area. Mexico also appears to have

gained from its participation in GVCs. US appears to be the only country which has high

participation in GVCs, has increased its exports to GDP ratio and also its domestic value-added

content in its exports. Country experiences therefore show that linking into GVCs may not bring

gains automatically. In fact, it makes aiming for trade- led growth more questionable!
